Types Of Suitcase Locks
Suitcase locks keep your belongings safe during travel. There are different types of locks used on suitcases. Understanding these helps you change the lock code easily.
This guide covers two common types: built-in combination locks and external TSA locks. Each type has its own way to change the code from the default 000.
Built-in Combination Locks
Built-in combination locks are part of the suitcase body. You see three or four rotating dials that show numbers. These locks start with the code 000 or 0000.

- Press or slide it while setting your new code.
- Turn the dials to your chosen numbers.

External Tsa Locks
External TSA locks attach to the suitcase zipper pulls. TSA agents can open these locks with a special key. You can set your own combination code for security.
| Feature | Built-in Combination Lock | External TSA Lock |
|---|---|---|
| Location | Inside suitcase body | Attached to zipper pulls |
| Reset Method | Reset button or lever | Small reset hole requiring a tool |
| TSA Access | May or may not have TSA key slot | Has TSA key slot |
| Code Format | 3 or 4 digit numbers | 3 digit numbers |
